I walked by this site today. Nothing new has happened, but with the building torn down and only the basement foundation remaining, it's quite obvious how much less work will need to be done when it comes to excavation.
The former Waterloo Lanes has some very active construction taking place today.
Tower crane going up today.
This place is using old style wooden forms for concrete:

Is this method going out of style? I was under the impression that
One Victoria used this technique as well
I got some photos of this project Friday morning, when I get a chance I will post them.

Sadly, it isn't.
What would you rather see?

Precast concrete or at least ICF both of which are superior.
Obviously faster, but what are other benefits?

(1) Concrete is rather sensitive to curing conditions. While nothing unsafe happens outdoors, properly temperature and humidity controlled cured concrete shows increased strength and lower permeability.
(2) There are decreases in quality when the concrete sits too long in the mixing truck. This is regulated so there is an expiry time for a load of concrete. If you use the load just within the time limit this is still safe, but nonetheless weaker concrete.
(3) The rebar placement shows less errors. My numbers are rather old, but I recall studies during demolition showing that a non negligible amount of rebar was out of place or improperly secured at cross members. ICF has guides that make sure rebar is where it is supposed to be, precast concrete is done at eye level in an enclosed facility usually with standard forms, so the probability of error is even lower.
(4) Less errors of alignment. You'd be surprised the number of walls which aren't true to the vertical.
(5) ICF: higher insulation factor.
